Ours is a cheapie cheapie one from Tesco which is fine but only takes very thin paper and thin Tesco brand laminator pouches. Anything more challenging, you have to get the iron out. (Yes, you can iron laminator pouches, if desperate. Hot iron, no steam.)
Anyhoo - want something more robust that will take thicker pouches etc. But not one of those A3 things that costs thousands. Any ideas?
